NAME

JSON::Schema::Modern::Result - Contains the result of a JSON Schema evaluation

VERSION

version 0.516

SYNOPSIS

use JSON::Schema::Modern;
my $js = JSON::Schema::Modern->new;
my $result = $js->evaluate($data, $schema);
my @errors = $result->errors;

my $result_data_encoded = encode_json($result); # calls TO_JSON

# use in numeric and boolean context
say sprintf('got %d %ss', $result, ($result ? 'annotation' : 'error'));

# use in string context
say 'full results: ', $result;

DESCRIPTION

This object holds the complete results of evaluating a data payload against a JSON Schema using JSON::Schema::Modern.

OVERLOADS

The object contains a boolean overload, which evaluates to the value of "valid", so you can use the result of "evaluate" in JSON::Schema::Modern in boolean context.

ATTRIBUTES

valid

A boolean. Indicates whether validation was successful or failed.

errors

Returns an array of JSON::Schema::Modern::Error objects.

annotations

Returns an array of JSON::Schema::Modern::Annotation objects.

output_format

One of: flag, basic, strict_basic, detailed, verbose, terse. Defaults to basic.

  • flag returns just the result of the evaluation: either {"valid": true} or {"valid": false}.

  • basic adds the list of errors or annotations to the boolean evaluation result.

    instance_location and keyword_location are always included, as json pointers, describing the path to the evaluation location; absolute_keyword_location is added (as a resolved URI) whenever it is known and different from keyword_location.

  • strict_basic is like basic but follows the draft-2019-09 specification precisely, including

    replicating an error fixed in the next draft, in that instance_location and keyword_location values are provided as fragment-only URI references rather than json pointers.

  • terse is not described in any specification; it is like basic, but omits some redundant

    errors (for example the one for the allOf keyword that is added when any of the subschemas under allOf failed evaluation).

METHODS

format

Returns a data structure suitable for serialization; requires one argument specifying the output format to use, which corresponds to the formats documented in https://json-schema.org/draft/2019-09/json-schema-core.html#rfc.section.10.4. The only supported formats at this time are flag, basic, strict_basic, and terse.

TO_JSON

Calls "format" with the style configured in "output_format".

count

Returns the number of annotations when the result is true, or the number of errors when the result is false.
